About JotTools

JotTools is a growing collection of free, fast, privacy-friendly online tools for PDFs, images, text, conversions, generators, calculators and developer tasks. The goal is simple: the everyday utility you need, in one place, without sign-ups, paywalls, or uploading your files to a stranger's server.

How it works

Almost every tool runs entirely in your browser. When you merge a PDF, resize an image, format JSON or generate a password, the work happens on your own device using modern web technology, so your files never leave your computer. That makes the tools fast, available offline after first load, and private by design.

Who builds it

JotTools is built and maintained by Bilgetek. We build practical software for writers, students, designers, developers and everyday users. JotTools brings free tools for working with files and text directly to your browser.

Why you can trust it

• Private: your data is processed locally and not stored on our servers.
• Free: no account, no trial, no hidden limits, supported by unobtrusive ads.
• Transparent: read our Privacy Policy and Terms.
• Improving: we add tools and refine existing ones regularly.
